I wanted to get my hands on a Tevo Little Monster a while back. I though I would have had a blast with one of them. I can't believe a printer this big came with a 3.5" display. So here is a side by side comparison of the 2 screens. On the left is the one that came with the printer that will never get used and on the right is the BigTreeTech TFT70 V3.0..

I have drawn up this mount for the 7" touchscreen that I will share on thingiverse as soon as it is done printing and I verify it fits right..
